Click-drag
Click-drag the selection tool (see red orange box below) to move in a more controlled fashion through the data. Choose the selection tool (default tool) and then click Click anywhere near the edge of the image. Keep the mouse pressed and drag the cursor (arrow) to the left or right. The display will continue moving at a steady pace for as long as the click-drag is held. This click-drag interaction is similar to the select-scrolling in many word processing programs, where you can select text and then, by continuing to select/drag the cursor up or down, you scroll through the document.
Grab-drag
This new feature debuted in IGB 6.5. Here, you select the Grab tool ("cartoon hand"'hand' icon; orange box) and click it within the display. Use it to drag the display in the direction you want to move.This is the opposite direction from click-drag movement, and can be more intuitive to some users. It also moves at the speed that the user moves the mouse, whereas click-drag moves at a steady pace. On the other hand, grab-drag can only move the image to the edge of the main window. You must re-grab to continue moving.
